In the crowd of all platformers, I have to say I liked the polish on this one. Animations felt right, enemies were interesting, the scribbles just rough enough to make the levels "believable": just before the tracking jumping enemy (for lack of a better name), there is no roof that I could see and I was thinking about what might lie on this unknown part of the paper. A very nice experience.

To be picky, I'd say that it is a bit short (of course the solution is easy) but also not very innovative. I would have loved fighting erasers, pencils and everything, breaking the third wall (I do not know how you transfer "breaking the forth wall" to a 2D game). That might be an idea for later :)

MacTuitui: I'd say that you can still break the fourth wall in a 2D game. The three other walls are the wall(s) to your left, the wall(s) to your right, and the wall that is a background to the screen; you play from the perspective of the fourth wall, which would block your view of the game were it visible.

Actually on-topic: ooh, love the graphical style. Shame it's so short, because you really nailed the feel of the running and jumping.
